Select ALL the computer types classified according to their principle of operation.

### Why this is right - **Analog computer** is correct because it represents information using continuously varying quantities. - **Digital computer** is correct because it processes information as discrete values. - **Hybrid computer** is correct because it combines analog and digital approaches. ### The concept Classification by principle of operation describes how a computer represents and processes information. An analog system works with continuous signals, while a digital system uses discrete values. A hybrid system combines characteristics of both. A laptop is instead a form factor, meaning a physical design category, not a principle-of-operation category. ### The other options - **D. Laptop computer**: A laptop is a portable computer design, not one of the three operation-based categories. ### Terms - **Analog computer**: A computer that processes continuously varying quantities. - **Digital computer**: A computer that processes discrete values. - **Hybrid computer**: A computer combining analog and digital processing. ### Remember Analog, digital, and hybrid describe operation; laptop describes physical form.
